Part Number: ISO5852S Tool/software: Hello everyone,
I'm working on an inverter design and need some advice on gate driver selection. My application involves driving an IGBT on the high side, with a DC supply voltage of 3.5kVDC. I'm considering the TI…
Part Number: ISO5852S-EP What's the value of the pull up resistor on the /RST input.
Is it the same value or 50kohms as pull up on /FLT and RDY pins.
It's not clear in the data sheet
Part Number: ISO5852S I used ISO5852S in my design to drive SiC. I am applying the PWM pulse to pin IN+ and IN+ (PIN 10 and 11).
I have also applied 2.5-5 V to Vcc1 and GND1 (15 and 9). Also, I am using +15 ; 0 ; -8 (VCC2 ; GND2 ; VEE2).
I am measuring the…
Part Number: ISO5852S-EP Other Parts Discussed in Thread: ISO5852S we are using a schottky diode ( NRVBAF3200T3G) across desat pin to limit the negative voltage spikes. As per the ISO5852S datasheet this pin will withstand up to -0.3V. as per the selected…
Part Number: ISO5852S Other Parts Discussed in Thread: UCC21750 A month ago, I started a thread here, describing the issue I was having with the IC. After a while and 20 hours of testing where everything was ok, The IC´s VCC and VEE pins got damaged without…
Part Number: ISO5852S Tool/software: Hi design experts,
I am designing a gate drive circuit for a full bridge converter. I want to supply -5V to+20V to each of the switches in the full bridge circuit as shown below. If there is any reference design,…
Part Number: ISO5852S-EP Other Parts Discussed in Thread: UCC21750 Hi Team,
We are using the part number ISO5852-EP. Followings are the technical question for the same part.
1. As per data sheet (VIT+UVLO) is typ-12V , Max-13V and (VIT-UVLO) is typ-9…
Hi Vitor,
When you say output current do you mean the output current of the gate driver?
The gate driver output current is determined by the resistance in the gate loop path. The 2.5A peak source is limited by the internal pull up MOSFETs so I'm not…
Part Number: ISO5852S I designed two gate drivers using the IC ISO5852S to be used in a half-bridge LLC resonant converter. One Gate drive is responsible for triggering two switches ( Working in parallel to divide the current on the switches) at the upper…
Part Number: UCC21750-Q1 Other Parts Discussed in Thread: UCC21750 , ISO5452 Tool/software: dear \sir,
i am using ISO5852-Q and want replace to UCC21750-Q1 only difference AIN pin1 connect with COM and pin16 APWM connect with VEE (-8v supply ) can keep…
